W's L/S Merino & Silk Base Layer in BlackMerino is legendary for its insulating and heat transferring properties. It's the gold standard for base layers for a reason. A fabric you don't see as often is silk, a material that human skin loves more than any other. Soar has blended these two natural fibers together to create a quick drying, moisture wicking longsleeve to get you through the winter in peak comfort. **Alex is 5' 10" and wearing a size Small** Four panel construction uses flatlock
